help straightening panorama

by highlandcream » Wed Apr 25, 2012 2:44 pm

Hi
Apologies i am relatively inexperienced at using gigapan.
I am having some problems straightening my panoramas.
I recently took a series of gigapixel panoramas (using a pano head) however when i stitch them using gigapan they are coming out curved or at an angle.
I have used the straightening tool for when the whole panoramic is at an angle but i was wondering if it is possible to change the anchor image to stop this from happening?
On the occasions where the panorama has come out curved i have used the vertical axis straightening tool but it often seems to make the problem worse.
Is there an alternative solution for straightening gigapixel panoramas?
Many thanks
Jasper

Are you using a manual or a robotic pano head?

Did you level the pano head before your shoot?

Can you show us a screenshot to demonstrate the problem you have?

Tip: use the Post reply rather than the Quick post option and you'll find an Image upload feature beneath the message edit box.

You can rotate the whole pano by adjusting the 'roll' angle.

To straighten out a curved horizon you have to change the centre point of the picture (vanishing point) by clicking just above or below the median line.

On a long pano you will probably not be able to sort it all out, but you can usually improve it quite a bit.
